Subject: Heads up: Logical Domains for sun4v platforms support in Nevada

With the putback of

     6391870 LDoms v1.0 Solaris Changes

Solaris Nevada now supports the Logical Domains (LDoms) feature. This
provides
the ability to create multiple software partitions on sun4v based
platforms.
Each of those partitions can run a separate instance of Solaris
without affecting
any other.

The LDoms product as a whole (Firmware and Solaris) implements the
following
ARC cases:
